What power supply do i need for this?

Im doing a fresh engine swap on my mustang and that means it time for a tuner, which in turn means car pc.

So after hrs of searching and reading i've decided on the Foxconn NTA350-0H0W-B-A-NA AMD Hudson D1. Its really just a mini-pc which should be more then enough for my needs. The issue im having now is how to power the damn thing when its in the car. It has a single dc input plug on that back and it includes a ac-dc power brick which is fine for home or bench use.

I looked at all the power supplies on mp3car store and couldnt really find anything that i though would work.

I dont need anything to crazy either, the monitor will be usb powered and the computer will never be doing anything to demanding. Just basic music, navi, wifi, and thats about it.

if you look at the specs of the power adapter, i believe it should say that it outputs 19v dc.

so that means that you require a dc-dc usb, carnetix 1900, or carnetix 2140 power supply.

and i don't recommend usb screens as the primary screen because you won't be able to see anything before the OS has fully loaded, or fails to load, so pc problems would require you to drag a second screen out to the car, or bring the whole pc into the house..

Well thats good news i thought it was gonna be something like that now i just need to figure out what adapter cable to get for the plug in.

Im going to use the usb monitor for use as essentially a handheld mouse/keyboard then ill have a normal monitor dash mounted. Im trying to limit the power demand as much as possible.

My car is being built for performance so being able to tune and listen to music is all i really want or need. Electric draw decreases spark output which for me isnt wanted. I already have a meaty ignition all msd but none the less.

I was a bit worried that the carnetix might not put out enough power on the secondary rail to power a monitor if the main rail is used for 19V however I haven't picked a monitor yet so have no idea what the power requirements of it are going to be.

I am running a 1900 for my HP [email protected] and using the 12v output for the screen with no power issues of. There is also a small 5v add on board that can be used to power the usb devices through a hub taking more load off of the PC if you wish.

Thanks for that, 3 amps just didn't seem like enough, I thought the monitor would have been one of the thirstier devices so to speak but my quick search never found any useful numbers to check. I am very tempted by having the three rails as you say.
Hmm more research required.
